[Mailman-Users] What do you think of this idea to keep external people from subscribing?

[Jessica Koeppel]

I've got a bunch of lists which I want to have set so that anyone can
subscribe themselves very easily.

However - I want only people on my internal network to be able to do this.

The web interface is accessible only internally, so that's easy.

But listname-request at foo.com is still there - random outsiders could
email that and get subscribed.

Would I lose anything *important* if I simply removed the listname-request
alias from my aliases, disabling that way of subscribing?
